SMC X-Ray Discrete Sources: 70 Compact Einstein IPC Sources

70 discrete X-ray sources from the Einstein IPC satellite in the direction of the Small Magellanic Cloud, tabulated by Wang & Wu (1992). The catalog is a service provided by NASA HEASARC, with full processing details available in the referenced publication. The data was last updated on the platform in March 2026.

Use Cases

• Cross-match and validate compact X-ray source catalogs based on the Einstein IPC observations.
• Study the distribution and properties of X-ray sources in the Small Magellanic Cloud based on the listed discrete sources.
• Perform statistical analysis of compact astrophysical sources based on the 70-object sample.

Strengths

• Contains 70 discrete sources, providing a focused sample for analysis.
• Derived from a peer-reviewed catalog published in the Astrophysical Journal Supplement Series.
• Sourced from NASA HEASARC, an authoritative provider of astrophysics data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal and instrumental bias inherent to the original Einstein IPC mission.
